Summary: | PROBLEM TO BE SOLVED: To provide a method for producing a polylactate-based polymer molded article which is not deformed by a thermal treatment and is highly crystallized to improve a load-deflection temperature. SOLUTION: This method for producing the biodegradable plastic molded article comprises mixing a polylactate-based polymer with 5 to 50 wt. % of lamellar graphite and then molding the obtained composition. The method for producing the polylactate-based polymer molded article preferably further comprises a step of thermally treating the composition at a temperature which is higher than the glass transition point of the polylactate-based polymer and lower than its melting point. The biodegradable plastic molded article is produced by the above method. COPYRIGHT: (C)2004,JPO |
